Advice on how to make my Goomy deck better!

I am new to the game overall, and love building decks. I know this one isn't currently legal, but I can still use it in expanded or league play. Logic was trainers that allowed for both more energy and card pulls, and then pokemon that were either Goomy, Goomy evolutions, or Gooey (AKA Ditto). Any and all advice is welcome!
